Severe COVID-19-related Pneumonia Seven Years after Heart Transplantation

A 67-year-old man on intense immunosuppressive therapy after heart transplantation for end-stage hypertrophic cardiomyopathy 7 years ago developed severe dyspnea and was admitted to our hospital. His serum severe acute respiratory syndrome coronavirus 2 antigen test was positive, and he was diagnosed with coronavirus disease 2019 (COVID-19)-related pneumonia. He was started on ventilatory management for severe respiratory failure and remdesivir for COVID-19, with careful adjustment of immunosuppressive drugs. However, unexpectedly prolonged muscle weakness necessitated transfer to a rehabilitation facility. Although the COVID-19 pandemic has subsided, it is still considered a risk in post-transplant cases. Infection control is considered critical in heart transplant recipients, especially in those receiving intensified immunosuppressive drugs.
